IMPROVED HEEL-PO LlsHiNe MACHINE.

To all whom t may coacem:

Be it known that we, J AMEs M. THoMPsoN, of Stoneham, in the county of Middlesex and State of Massachusetts, and S. D. TRIPP, of

Massachusetts, have invented a new and Improved Machine for Polishing the Edges of the Soles of Boots and Shoes; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being lhad to the accompanying drawings, forming part of this specication, in which- Figure 1 is an elevation of our invention; Fig. 2, a horizontal section of the sama-,taken in the line w a', Fig. l.

Similar letters of reference indicate corresponding parts.

The object of this invention is to obtain a new and useful device for polishing the edges of the soles of boots and shoes', one Which may bc manipulated with the greatest facility and perform its work in an expeditious and perfect manner, and be capable of being adjusted to operate upon soles of greater or less thickness. l

A A represent two uprights, which are secured to a base, B, or any proper xture, and O is a horizontal shaft which has 4its bearings in the uprights A A and is allowed to slide freely therein.

On one end of this shaft O there is tted a circular disk, D, loosely, so that it may rotate freely on the shaft, and to the upright A there is attached a gage, E, said gage being underneath shaft C, and grooved at its upper surface for the shaft O to work in, forming a bearing for the shaft as well as a gage for the The spaces between the disk D and the end of the gage may be regulated as desired by adjusting the shaft O longitudinally, which is done by having a shaft, F, placed in the upriglits A A underneath the shaft O, said shaft F having an upright plate, aat its outer end, which fits in a groove, b, in a collar, c, on shaft O, and the shaft F provided with a handle, d, for the convenience of moving it. By this means the shaft C may be moved longitudinally with the greatest facility, and the length of this movement is limited by the drivin g-pulley e and a collar, f, on shaft O between the uprightsA A.

G represents a metal frame or bar, which is bent or curved to form two arms, g g', about lat right angles with each other. The upper arm, g, is suspended by a spiral. spring, H, from a hook, I, at the top of the upright A, and in the lower arm, g', the arbor h of a circular disk, J, is fitted and allowed to rotate freely. This disk J has a dovetail slot, z', made in it and extending entirely across it centrally, and in this slot a plate, K, is fittedand allowed to slide freely, said plate having a handle, j, at each end of it for the convenience of moving'it.

To the sliding plate K the boot or shoe to be operated upon is attached. i

The operation is as follows: The shaft() is rotated by any proper means, and the spring H hasa tendency to keep the edge of the solein contact with the shaft O, the disk D working in the crease between the sole and the upper, and the bottom of the sole bearin g against the gage E, the plate K being moved in the disk J and said disk turned by one hand of the operator while the other hand adjusts vthe shaft C, it grasping the handle d of shaft F. Thus by this simple arrangement the edge of the sole of the boot or shoe may be polishefd with the greatest facility and in a perfect manner.

The frame or bar G has a guide, L, attached to it, which extends down and then projects laterally toward the upright A and is bent to form a loop, or is slotted to fit on a pin, e, on the base B.

In case light or thin soles are to be polished they may be directly applied to the end of the shaft O, where the collar c is affixed, and this collar may be loosened so as to serve as a gage for the bottom ofthe sole to press against, the shaft C being held from moving longitudinally by adjusting the collar f so that it will be in contact With the upright A', the shaft C having been previously moved so that the pulley c will bein contact with upright A.

We design to have the shaft O kept cool bya blast ot air forced-down upon it at the part ai gninst which the sole of the shoe bears through :t tube, cox.

We claim as nen7 and desire to secure by Letters Patentl. The loose disk D, placed at one end of -tlle rotating polishing-shaft C, in connection with the gage E, substantially as and forthe purpose specified.

2. In connection with thepolishing-shaift C, the frame or barG, suspended by ai spring, H, from an upright, A, or other fixture, and provided With a rotating disk, J, in which st sliding plate, K, is tted, having the boot or shoe attached, substantially as and for the purpose set forth. v

3. The supplemental shaft F, in combination with the polishingshaft C and the frame or bar G, provided with the disk J, containing the sliding1 plate K, substantially as and for the `purpose specified.
